AbstractTwo nematode species of the family Cystidicolidae were collected from the digestive tract of marine fishes off New Caledonia, South Pacific: Ascarophis adioryx Machida, 1981 from the stomach of the speckled squirrelfish Sargocentron spiniferum and the sabre squirrelfish Neoniphon sammara (new host record) (both Holocentridae, Beryciformes), and a Spinitectus sp. female, morphologically similar to S. beaveri Overstreet, 1970, from the roundjaw bonefish Albula glossodonta (Albulidae, Albuliformes). Based on light and scanning electron microscopy examinations, A. adioryx is redescribed and a new subgenus Dentiascarophis subgen. nov., characterized by the presence of one dorsal and one ventral median protrusions in the mouth, is established to accommodate it; a key to subgenera of Ascarophis is provided. Ascarophis holocentri Parukhin, 1984 is considered a junior synonym of A. adioryx. The cephalic structure of Spinitectus sp. and S. beaveri is very different from those in other congeners and, therefore, a new subgenus Paraspinitectus subgen. nov., characterized by highly reduced pseudolabia, is erected to accommodate these species. The hemiurid digenean Lecithochirium cirrhiti (Manter et Pritchard, 1960) Yamaguti,1970 was found in the stomach of three species of squirrelfishes. Findings of A. (D.) adioryx, Spinitectus (P.) sp. and L. cirrhiti in New Caledonian waters represent new geographical records of these parasites.

AbstractParasitological examination of the freshwater fish Tetraodon palembangensis Bleeker (Tetraodontidae, Tetraodontiformes) (n = 19), imported along with other ornamental fishes from Thailand into the Czech Republic in October 1998, revealed the presence of male specimens of the nematode Dichelyne (Dichelyne) hartwichi Moravec, Wolter et Körting, 1999 (Cucullanidae) (prevalence 11%, intensity 1). Their detailed study using light and scanning electron microscopy (the latter used for the first time in this species) enabled the redescription of this hitherto little-known species and the recognition of considerable morphological and biometrical intraspecific variability. The finding of this species in T. palembangensis represents a new host record.

Abstract One new and one known species of parasitic nematodes are reported from Thailand for the first time: Falcaustra kaverii (Karve et Naik,1951) (Kathlaniidae) from the intestine of the freshwater fish Poropuntius deauratus (Valenciennes) (Cyprinidae) (new host record) and Ascarophis scatophagi sp. nov. (Cystidicolidae) from the intestine of the marine fish Scatophagus argus (Linnaeus) (Scatophagidae). The morphology of both these species was studied with the use of light (LM) and scanning electron microscopy (SEM) (the latter method used for F. kaverii for the first time). The new species (A. scatophagi) is mainly characterized by nonfilamented, markedly elongate-oval eggs (size 42–45 × 18 μm), spicules 555–642 μm and 105–150 μm long, the muscular/glandular oesophagus length ratio (1:13–34), bifurcate deirids, the length of the female tail (159–249 μm) and cephalic structures typical of the nominotypical subgenus Ascarophis. Representatives of Falcaustra Lane, 1915 and Ascarophis van Beneden, 1871 were not previously reported from fishes in Thai waters.

AbstractExaminations of marine fishes off New Caledonia, South Pacific, carried out in 2003–2006, yielded some nematodes of the genus Philometra Costa, 1845, including the following three new species: P. cyanopodi sp. nov. (males and subgravid females) and P. lethrini sp. nov. (males and subgravid females) from the gonads of Epinephelus cyanopodus (Richardson) (Serranidae) and Lethrinus genivittatus Valenciennes (Lethrinidae), respectively, and P. lagocephali sp. nov. (gravid female) from the abdominal cavity of Lagocephalus sceleratus (Gmelin) (Tetraodontidae). Another congeneric species P. fasciati sp. nov. from the gonads of Epinephelus fasciatus (Forsskål) (Serranidae), originally reported as P. lateolabracis (Yamaguti, 1935), has been established with reference to the description of males and a mature female published by Moravec and Justine (2005). The new species are characterized mainly by the length of spicules and the length and structure of the gubernaculum, structure of the male caudal end (except for P. lagocephali), body size, location in the host and by the types of hosts. In addition, Philometra sp. (subgravid females) from the gonads of Lutjanus vitta (Quoy et Gaimard) (Lutjanidae) and Philometra cf. ocularis Moravec et al., 2002 (gravid female) from the oculo-orbit of Epinephelus areolatus (Forsskål) were found, the latter representing a new host record.

Recent examinations of anisakid nematodes (Anisakidae) from marine fishes off New Caledonia, collected in the years 2003–2008, revealed the presence of the following five new species of Raphidascaris Railliet et Henry, 1915, all belonging to the subgenus Ichthyascaris Wu, 1949: Raphidascaris (Ichthyascaris) spinicauda n. sp. from the redbelly yellowtail fusilier Caesio cuning (Caesionidae, Perciformes); Raphidascaris (Ichthyascaris) fasciati n. sp. from the blacktip grouper Epinephelus fasciatus (Serranidae, Perciformes); Raphidascaris (Ichthyascaris) nudicauda n. sp. from the brushtooth lizardfish Saurida undosquamis (Synodontidae, Aulopiformes); Raphidascaris (Ichthyascaris) euani n. sp. from the Japanese large-eye bream Gymnocranius euanus (Lethrinidae, Perciformes); and Raphidascaris (Ichthyascaris) elopsis n. sp. from the Hawaiian ladyfish Elops hawaiensis (Elopidae, Elopiformes). An additional two congeneric species, R. (I.) etelidis Moravec et Justine, 2012 and R. (I.) sillagoides (Bruce, 1990) were found in the deep-water red snapper Etelis carbunculus (new host record) and the deepwater longtail red snapper Etelis coruscans (both Lutjanidae, Perciformes), and the silver sillago Sillago sihama (Sillaginidae, Perciformes) (new host and geographical records), respectively. Two unidentified congeneric species, Raphidascaris (Ichthyascaris) sp. 1 from the trumpet emperor Lethrinus miniatus (Lethrinidae, Perciformes) and Raphidascaris (Ichthyascaris) sp. 2 from the white-spotted puffer Arothron hispidus (Tetraodontidae, Tetraodontiformes) were recorded. Moreover, two species of Hysterothylacium Ward et Magath, 1917, H. alatum Moravec et Justine, 2015 and H. epinepheli (Yamaguti, 1941), were found in the leopard coralgrouper Plectropomus leopardus (type host) and the highfin grouper Epinephelus maculatus (new host) (both Serranidae, Perciformes), respectively. This is the second finding of H. epinepheli since its original description in Japan 79 years ago. Most species are described based on light and electron microscopical studies.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

In the state of Rio Grande do Sul, there are few records of geographical distribution and host plants to species of Tomoplagia Coquillett, as well as other genera of Tephritidae, especially those associated with plants of the family Asteraceae. Here, we report the first occurrence of Tomoplagia rudolphi (Lutz & Lima, 1918) in the state of Rio Grande do Sul, inducing stem galls in Vernonanthura tweediana (Baker) H. Rob. (Asteraceae, Vernonieae), whose plant becomes a new host record for this species. In this way, is increased to nine species of Tomoplagia recorded for Rio Grande do Sul. Biological and morphological data and photos of gall, larvae, pupae at new host and distribution map of the species in Brazil are provided.

AbstractThe cephalic end of the type species of pharyngodonid genera Travnema and Cosmoxynemoides, T. travnema Pereira, 1938 and C. aguirrei Travassos, 1949, parasites of Brazilian freshwater fishes, was studied by scanning electron microscopy. The mouth aperture of Travnema was found to be circular, surrounded by four cephalic papillae and two lateral amphids and the cuticle of the cephalic end had a conspicuous dense sculpture. On the other hand, the mouth aperture of Cosmoxynemoides was triangular, surrounded by three lip-like elevations covering the whole surface of the relatively flat cephalic extremity, each with two inner lobes separated one from another by a short groove; the lip-like elevations bore four medium-sized, kidney-shaped cephalic papillae and two minute amphids (two papillae on the dorsal elevation and one papilla and one amphid on each of two ventrolateral elevations); the cuticle of the cephalic end was smooth. Both species were noted for the absence of oral lamellae and the presence of lateral alae. Both genera are listed in the family Pharyngodonidae but Travnema (and also Hakynema), due to its morphological peculiarities, is considered to represent a distinct subfamily Travnematinae within the Pharyngodonidae. The finding of both T. travnema and C. aguirrei in the characid fish Astyanax bimaculatus lacustris represents new host records.

AbstractTwo little-known nematode species of the family Camallanidae, intestinal parasites of marine perciform fishes, are reported from off New Caledonia: Procamallanus (Procamallanus) annulatus Yamaguti, 1955 from the goldenlined spinefoot Siganus lineatus (Valenciennes) (Siganidae) and Procamallanus (Spirocamallanus) monotaxis (Olsen, 1952) from the longspine emperor Lethrinus genivittatus Valenciennes and the slender emperor Lethrinus variegatus Valenciennes (both Lethrinidae). Detailed light and electron microscopical studies (the latter used for the first time in these species) revealed some taxonomically important, previously not observed features, such as the presence of deirids, six crescent-shaped elevations surrounding the mouth, three poorly developed protuberances on the female tail tip and circumcloacal papillae and phasmids on the male tail in P. annulatus, and the presence of a circumoral flange, only 12 (instead of 14 reported) cephalic papillae, the shape of deirids and similar numbers (14–17 and 14–15) of spiral ridges in the male and female buccal capsules in P. monotaxis. The fourth-stage larva of P. annulatus is described for the first time. Firststage larvae of both species were found to possess several digital processes at the tail tip. The present findings represent new host and geographical records of these parasite species.

AbstractFalcaustra papuensis sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Sphenomorphus simus (Squamata, Sciencidae) is described and illustrated. Falcaustra papuensis represents the 4th Australo-Papuan species assigned to this genus and is distinguished from other Australo-Papuan species by the distribution pattern of caudal papillae (6 precloacal, 6 adcloacal, 8 postcloacal, and 1 median), length of spicules (561–714 μm) and presence of a pseudosucker. Sphenomorphus simus was found to harbor 2 additional species of nematodes, Meteterakis crombiei and Oswaldocruzia bakeri. Sphenomorphus simus represents a new host record for each of these nematode species.
